Sivu 43 - Borax and boric acid, when given in quantities equal to 1.5-2.0 per cent of the daily food are liable to produce nausea and vomiting. Owing to the rapid elimination of both borax and boric acid, no marked cumulative action can result from their daily ingestion in moderate quantities. At no time in these experiments was there any indication of abnormality in the urine ; albumin and sugar were never present.
Sivu 415 - The retarding influence of acid-proteids is out of all proportion to their power of destruction. Large percentages, however, of acid-proteids may cause almost complete destruction of the ferment. 10. The most favorable condition for the diastatic action of ptyalin, under most circumstances, appears to be a neutral condition of the fluid together with the presence of more or less proteid matter. The addition of very small amounts of hydrochloric acid, however, to dilute solutions of saliva, giving...
Sivu 161 - Moreover, the comparative poverty of many species in proteids is corroborated by the results of other investigations now in progress in this laboratory, the yield of isolated substance being quite small. The fungi thus form no exception to the ordinary classes of fresh vegetable foods ; indeed, they take a decidedly inferior rank in comparison with many. The carbohydrate content of the fungi is relatively high ; but until more is known regarding the nature and digestibility of the carbohydrate constituents...
Sivu 397 - J while engaged in the study of the digestive products of casein, carried out a series of analyses of the insoluble residue corresponding to Lubavin's dyspeptone. His preparations contained an average content of phosphorus amounting to 2.57 per cent. It was pointed out, however, that in every case the phosphorus found in the ash of the products analyzed was as great as the total phosphorus observed and Chittenden arrived at the conclusion " that instead of being a phosphorized compound, it (dyspeptone)...
Sivu 272 - A glance through these results shows at once certain marked differences in the character of the saliva obtained under the different conditions specified. Thus, saliva which flows from the mouth after the latter has been rinsed once with water invariably shows a lower degree of alkalinity and generally contains a smaller percentage of solid matter than the secretion obtained by the other methods. In amylolytic power, however, there is great variation, some samples showing a relatively strong amylolytic...
Sivu iii - University, a series of volumes has been prepared by a number of the Professors and Instructors, to be issued in connection with the Bicentennial Anniversary, as a partial indication of the character of the studies in which the University teachers are engaged.
Sivu xvi - A Further Study of the Influence of Alcohol and Alcoholic Drinks upon Digestion, with Special Reference to Secretion.
Sivu iii - Sons, of New York. With the approval of the President and Fellows of Yale University, the series has been prepared by a number of the Professors and Instructors, to be issued in connection with the Bicentennial Anniversary, as a partial indication of the studies in which the University teachers are engaged. The list of volumes includes some of a special and technical nature, others of a more general character.
Sivu 124 - Of hastened digestion, the results obtained give little or no suggestion, and we must therefore conclude that the two diverse factors above referred to more or less counterbalance each other so that gastric digestion in the broadest sense of the term is not markedly varied under the influence of alcohol or alcoholic fluids. This conclusion, it may be mentioned, stands in perfect harmony with the results of the investigations of Zuntz and Magnus-Levy regarding the influence of alcohol (beer) on the...
